Abstract

Provided is an image processing device which can improve the optical flow calculation accuracy upon calculation of an optical flow in a window unit.  The image processing device uses a plurality of images captured at different times to calculate an optical flow in accordance with image information in the window for an object to be processed.  The image processing device includes: a position acquisition means which acquires position information relating to the object to be processed; and a setting means which sets the window size for calculating the optical flow in accordance with the position information acquired by the position acquisition means.
